How to do getUserRowColumnChoice() function?

Question

I got stuck at how to set up the correct expession for While loop so that the player needs to keep clicking until they click in an empty square.

Answer 1

you want them to keep clicking untill they click a blank square, which is represented by ' ' in the matrix. so the loop should run while ' ' != gameBoard[ ][ ] , with the correct [ ] from the function call.

Side note: you could also do

while <choice> == 'X' or <choice> == 'O':

However, != ' ' is simpler.
